Description

The Stillen Adjustable Sway Bar Kit offers a significant upgrade for your Nissan 370Z, Infiniti G35, or G37, enhancing cornering, stability, and overall handling. Constructed from high-strength aircraft-grade steel with a thicker wall for increased stiffness, these sway bars retain a nearly factory outer diameter. This allows for the reuse of factory bushings, avoiding the squeaking and maintenance issues often associated with aftermarket urethane bushings. The bars also feature factory-style bushing collars to prevent movement during hard cornering. Each kit is manufactured in-house by Stillen, ensuring quality control throughout the production process, and finished with a durable red powder coat for corrosion resistance. The front sway bar offers 5-way adjustability, providing stiffness increases from 21-48%, while the rear sway bar offers 3-way adjustability with stiffness increases from 37-70%. These adjustments allow for precise tuning of your vehicle's suspension dynamics. This kit is specifically designed for the following RWD models: 2009-2020 Nissan 370Z, 2003-2008 Infiniti G35 Sedan RWD, 2008-2013 Infiniti G37 Sedan RWD, 2014-2015 Infiniti Q40 RWD, and 2014-2015 Infiniti Q60 RWD. Please note that this kit is NOT FOR AWD MODELS.
